自动门微波传感器原理

The Principle of Microwave Sensor for Automatic Door

自动门微波传感器是采用多普勒原理的一种自动门微波传感器。自动门微波传感器是利用微波的传输性能好、易反射、被吸收功率易测量等特点,用专门的微波振荡器来产生微波,特定的天线收发微波。

The automatic door with microwave sensor is an automatic door of microwave sensor that adopts the Doppler principle. By using the advantages of good transmission performance, easy reflection, easy measurement for absorbed power and so on of the wave, the automatic door sensor makes microwave with the specific microwave oscillator, receiving and sending microwave with the specific antenna.
